STEM ADJUSTMENT
To raise or lower your stem, use an adjustable wrench or Allen wrench on the stem bolt to loosen the stem
(see Figure 54). Do not remove this bolt completely, as the stem wedge may fall inside your frame. Make
sure the stem is inserted enough so that the minimum insertion marks on your stem are completely
covered (see Figure 55).
WARNING: To prevent steering system damage and possible loss of control, the stem and handlebars
must be properly adjusted and tightened. DO NOT OVERTIGHTEN (see Page 106, Figure 25).
WARNING: To prevent steering system damage and possible loss of control, the stem must be inserted
enough so that the minimum insertion marks are completely covered.
WARNING: Do not over tighten the stem bolt. Over tightening the stem bolt can damage the steering
system and cause a loss of control. If necessary re-adjust the handlebar and tighten the handlebar
clamp nut.
WARNING: Threadless stem systems cannot be raised or lowered without removing components and
re-adjusting. They should not be adjusted or loosened by anyone other than an experienced bicycle
shop mechanic (see Figure 56).
HANDLEBAR ADJUSTMENT
To adjust the handlebars forward and backwards, loosen the stem bolt or bolts. Your bike may have one
(see Figure 57), two (see Figure 68), or four (see Figure 59) bolts holding the handlebar in place. Do not
completely remove these bolts, simply loosen them until you are able to move the handlebar to the
desired position. Once complete, tighten the bolt(s). If your stem has multiple bolts, be sure to tighten
them evenly (alternating each bolt a few turns at a time).
To test the tightness of the handlebar, hold the bike stationary and try to rotate the ends of the handlebar
up and down or move the bar forward and back. If the handlebar moves, loosen the handlebar clamp nut
or bolts evenly to re-position and then re-tighten. Repeat the test until the bars will not move.
